Description

Technical Field

[0001] The invention belongs to the technical field of PE water supply pipe grinding, and in particular relates to a pipe end grinding device based on the production of PE water supply pipes. Background Art

[0002] PE pipe is a plastic pipe widely used in water supply, drainage, gas transmission and other fields. It is mainly made of polyethylene material and has the characteristics of light weight, corrosion resistance and good flexibility. During the construction of PE water supply pipes, multiple PE pipes are usually connected to meet the length requirements. Before connection, the two ends of the outer ring of the PE pipe need to be ground to ensure the stability and sealing of the connection.

[0003] The existing grinding method usually uses sandpaper for manual grinding or workers use a handheld grinder for grinding.

[0004] The existing grinding method has the following shortcomings:

[0005] 1. Whether it is polished with sandpaper or a grinder, the two ends of the PE pipe can only be polished separately during polishing. The two ends of the PE pipe cannot be polished at the same time. The polishing speed is slow and the construction efficiency is low;

[0006] 2. When the existing grinding method is used for grinding, the PE pipe is prone to deviation, resulting in low grinding accuracy, and it is difficult to control the grinding degree of each part of the outer ring of the PE pipe to be consistent with the existing grinding method. These problems will lead to poor stability and sealing of the PE pipe after docking.

[0007] 3. When the existing grinding method is used for grinding, the grinding length of the PE pipe port is difficult to control. If the grinding length is too long, part of the ground PE pipe will be exposed outside the butt joint, and the wear resistance and corrosion resistance of the ground PE pipe will be reduced, thereby affecting the service life. If the grinding length is too short, it will affect the stability and sealing of the PE pipe after docking. Summary of the invention

[0008] The purpose of the present invention is to provide a pipe end grinding device based on the production of PE water supply pipes in response to the problems raised in the above background technology.

[0020] Furthermore, the locking unit includes a through slot formed on the second bevel gear, and a locking screw is threadedly connected to a side wall of the through slot close to the first rotating shaft.

[0021] Furthermore, the transmission component includes a first column gear fixedly connected to the conveyor belt driving shaft, and a second column gear meshing with the first column gear is fixed on the second rotating shaft.

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] 1. The present invention grinds the PE pipe by an annular sanding belt. The annular sanding belt contacts two arc surfaces with the PE pipe. When the annular sanding belt rotates, the two contact arc surfaces can be grinded at the same time, thereby improving the grinding speed. In addition, the present invention grinds both ends of the PE pipe at the same time, thereby further improving the grinding speed and thus improving the construction efficiency of the water supply pipe.

The fixed component ensures that the pipe will not shift when the PE pipe is polished, and the polishing accuracy is high. When the motor stops working, the electromagnetic spring is powered off and shortened, and the fixed component releases the fixation of the PE pipe, so that the polished PE pipe can be directly removed, which is convenient for installation and disassembly and has high work efficiency.

[0025] 3. The present invention arranges a reciprocating screw, and the second rotating shaft drives the sleeve to rotate through a flat key. Under the action of the reciprocating screw, the sleeve rotates and reciprocates horizontally along the axis direction of the second rotating shaft. The grinding length of the PE pipe port is fixed, and the grinding length will not be too long or too short, thereby ensuring the stability and sealing of the PE pipe after docking, and can increase the service life of the PE pipe.

[0026] 4. The present invention provides an adjustment component and a locking unit. For the grinding of PE pipes with different diameters, the locking screw can be rotated to release the lock on the second bevel gear, and then the handle is rotated to drive the screw to rotate. The two sliders are driven to move in opposite directions through the cooperation of the sliding sleeve and the connecting rod, so as to adjust the distance between the two sliders, so that the device is suitable for grinding PE pipes with different diameters and has a wide range of applications.

[0027] 5. The present invention sets a waste collection component. When the second rotating shaft rotates, it drives the conveyor belt to operate. The waste generated during grinding falls on the conveyor belt and moves with the conveyor belt. Finally, the waste falls into the collection tank, which is convenient for centralized treatment of the waste, saves the time of cleaning the workbench after the grinding work is completed, and further improves work efficiency.

[0041] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0042] like Figure 1-Figure 8 As shown, a pipe end grinding device based on the production of PE water pipes includes a workbench 1, a fixed component, a rotating component, a grinding component and a waste collection component. The workbench 1 is provided with a plurality of weight-reducing grooves, which are used to reduce the materials required for the production of the equipment and reduce the weight of the equipment, thereby reducing the production cost and transportation cost of the equipment. A support leg is provided under the workbench 1, and a mounting hole is provided at the bottom of the support leg.

[0043] The fixing assembly includes two support plates 2 fixed on the workbench 1, and a hollow column 21 is rotatably connected to the support plate 2. A clamping component is provided in the hollow column 21. The clamping component includes a plurality of mounting seats 22 fixed in the hollow column 21, and a movable plate 23 is rotatably connected to the mounting seat 22. A rubber strip 24 is fixed on the movable plate 23. An electromagnetic spring 25 is fixedly connected between the movable plate 23 and the hollow column 21. When the electromagnetic spring 25 is energized, it will extend under the action of the magnetic field. Conversely, when the power is off, the electromagnetic spring 25 will shorten under the action of the magnetic field.

[0044] During operation, the electromagnetic spring 25 is energized and extends, thereby driving the movable plate 23 to rotate, and the rubber strip 24 contacts the PE tube and clamps the PE tube to ensure that the PE tube will not deviate during the grinding process, thereby improving the grinding accuracy. After the grinding work is completed, the electromagnetic spring 25 is de-energized and shortened, and the rubber strip 24 automatically releases the fixation of the PE tube, which is convenient for the fixation and removal of the PE tube.

[0045] The rotating assembly includes a motor 31 fixed on the workbench 1. The circuit connection between the motor 31 and the electromagnetic spring 25 is in series. The output end of the motor 31 is connected to the first rotating shaft 32 through a coupling. A worm 33 is fixed on the first rotating shaft 32. An annular groove is opened on the side wall of the hollow column 21. A worm wheel 34 adapted to the worm 33 is fixedly connected in the annular groove.

[0046] During operation, the motor 31 is energized to drive the first rotating shaft 32 and the worm 33 to rotate, thereby driving the worm wheel 34 and the hollow column 21 to rotate. The reduction transmission mechanism of the worm 32 and the worm wheel 34 is utilized to make the hollow column 21 rotate slowly and uniformly, so that the polishing degree of each part of the outer ring of the PE pipe is consistent.

[0047] The grinding assembly includes two guide rails 41 fixed at both ends of the workbench 1, two sliders 42 are slidably connected to the guide rails 41, a reciprocating screw 43 is fixed to the slider 42, a nut 44 is threadedly connected to the reciprocating screw 43, a sleeve 45 is fixed to the nut 44, and an annular abrasive belt 46 is sleeved on the two sleeves 45. The grinding assembly also includes an adjustment component driving component, the adjustment component includes a fixed block 40 fixed to the guide rail 41, a threaded rod 401 is rotatably connected to the fixed block 40, and the threaded rod 40 A handle 402 is provided at one end away from the fixed block 40, a sleeve 403 is threadedly connected to the threaded rod 401, a connecting rod 404 is rotatably connected to the sleeve 403, and one end of the connecting rod 404 away from the sleeve 403 is rotatably connected to the reciprocating screw 43, and the driving component includes a second rotating shaft 451 slidably connected to the sleeve 45, key slots are provided at both ends of the second rotating shaft 451, a flat key 452 is fixed in the key slot, and a sliding groove is provided on the inner wall of the sleeve 45, and the flat key 452 is slidably connected to the sliding groove.

[0048] Before work, the handle 402 is rotated according to the diameter of the PE pipe to be polished to drive the threaded rod 401 to rotate, thereby driving the sliding sleeve 403 to move horizontally along the threaded rod 401, and the two sliders 42 are moved to appropriate positions under the action of the connecting rod 404. During work, the second rotating shaft 451 drives the flat key 452 to rotate, thereby driving the sleeve 45 to rotate. The rotation of the sleeve 45 drives the annular sanding belt 46 to rotate to polish the PE pipe. While the sleeve 45 rotates, under the action of the reciprocating screw 43, the sleeve 45 moves horizontally back and forth along the axial direction of the reciprocating screw 43, so that the polished length of the PE pipe port is fixed.

[0049] The waste collection assembly includes a slide rail 51 fixed on the workbench 1, a base plate 52 is slidably connected to the slide rail 51, a conveyor belt 53 is provided on the base plate 52, one end of the driving shaft of the conveyor belt 53 is rotatably connected to the slider 42, and a collecting trough 54 is provided on the base plate 52. The waste collection assembly also includes a transmission component, the transmission component includes a first column gear 55 fixedly connected to the driving shaft of the conveyor belt 53, and a second column gear 56 meshing with the first column gear 55 is fixed on the second rotating shaft 451.

[0050] During operation, the second rotating shaft 451 rotates to drive the first column gear 55 to rotate. Under the action of gear meshing, the second column gear 56 drives the driving shaft of the conveyor belt 53 to rotate, and the conveyor belt 53 starts to run synchronously. The waste dropped during grinding falls on the conveyor belt 53 and moves with the conveyor belt, and finally falls into the collecting trough 54, thereby realizing centralized cleaning of the waste.

[0051] The working principle of the present invention is as follows:

[0052] Before work, first tighten the locking screw 4542 to release the fixing of the second bevel gear 454 by the locking screw 4542, so that the second bevel gear 454 can move horizontally along the first rotating shaft 32, and then rotate the handle 402 to drive the threaded rod 401 to rotate, thereby driving the sliding sleeve 403 to move horizontally along the threaded rod 401, and under the action of the connecting rod 404, the two sliders 42 are moved closer to or away from each other along the guide rail, and the two sliders 42 are moved to appropriate positions according to the diameter of the PE pipe to be polished, and then tighten the locking screw 4542 to fix the second bevel gear 454. By changing the positions of the two sliders 42, the device is suitable for polishing PE pipes of different diameters, and has a wide range of applications. At the same time, since the driving shaft of the conveyor belt 53 is rotatably connected to one of the sliders 42, the conveyor belt 53 is driven to move synchronously when the slider 42 moves, thereby ensuring that the first column gear 55 and the second column gear 56 are always in a meshing state.

[0053] During operation, the PE tube is passed through the hollow column 21, and the two ends of the PE tube are respectively passed through two annular sanding belts 46, and then the motor 31 is turned on. When the motor 31 is turned on, the electromagnetic spring 25 is energized. After being energized, the electromagnetic spring 25 extends under the action of the magnetic field, thereby driving the movable plate 23 to rotate, and the rubber strip 24 contacts the PE tube and clamps the PE tube to fix the PE tube, ensuring that the PE tube will not deviate during the grinding process, and the grinding accuracy is high. After the grinding work is completed, the motor 31 is turned off, and the electromagnetic spring 25 is synchronously powered off. After the electromagnetic spring 25 is powered off, it shortens under the action of the magnetic field, thereby driving the movable plate 23 to rotate in the opposite direction, and the rubber strip 24 is separated from the PE tube to automatically release the fixation of the PE tube, which is convenient for fixing and disassembly of the PE tube and improves work efficiency.

[0054] After the motor 31 is energized, it drives the first rotating shaft 32 and the worm 33 to rotate, thereby driving the worm wheel 34 and the hollow column 21 to rotate. The rotation of the hollow column 21 drives the PE pipe fixed in the hollow column 21 to rotate. The reduction transmission mechanism of the worm 32 and the worm wheel 34 is used to make the PE pipe rotate slowly and uniformly, so that the polishing degree of each part of the outer ring of the PE pipe is consistent, ensuring the stability and sealing of the PE pipe after docking. While the first rotating shaft 32 rotates, the second rotating shaft 451 rotates synchronously under the meshing action of the first bevel gear 453 and the second bevel gear 454. The second rotating shaft 451 drives the flat key 452 to rotate, thereby driving the sleeve 45 to rotate. The rotation of the sleeve 45 drives the annular sanding belt 46 to rotate to grind the PE pipe. During grinding, the annular sanding belt 46 contacts two arc surfaces with the PE pipe. When the annular sanding belt 46 rotates, the two contacting arc surfaces are polished at the same time, thereby improving the grinding speed. In addition, both ends of the PE pipe are polished at the same time, further improving the grinding speed, thereby improving the construction efficiency of the water supply pipe.

[0055] While the sleeve 45 rotates, under the action of the reciprocating screw 43, the sleeve 45 reciprocates horizontally along the axial direction of the reciprocating screw 43, so that the annular sanding belt 46 grinds different positions of the PE pipe port, and since the length of the reciprocating screw 43 is fixed, the grinding length of the PE pipe port is fixed, and the grinding length will not be too long or too short, thereby ensuring the stability and sealing of the PE pipe after docking, and can increase the service life of the PE pipe.

[0056] When the second rotating shaft 451 rotates, it drives the first column gear 55 to rotate. Under the action of gear meshing, the second column gear 56 drives the driving shaft of the conveyor belt 53 to rotate, and the conveyor belt 53 starts to operate synchronously. The waste dropped during grinding falls on the conveyor belt 53 and moves with the conveyor belt, and finally falls into the collecting trough 54, thereby realizing centralized cleaning of the waste, saving the time of cleaning the workbench after the grinding work is completed, and further improving work efficiency.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
